Avionics map mainly presents the aviation-related topographic factor and aviation factor, and can be used to study the aviation area, determine the routes and the aircraft position and flight direction as well as the implementation of the air commands. It is embedded in the carrier equipment as a database, which can be used as an important signal source and reference point for communications, navigation, guidance and control systems, to complete the system functions and fly missions with them. The digital elevation model and database development are key technologies of the avionics map research. Avionics map has broad application prospects in the flight simulator simulation, battle command, and weapons systems terrain contour matching navigation.
